Active clinical trials for "Arrhythmias, Cardiac"

The purpose of this study is to investigate whether a 3 month treatment course of low-dose Colchicine decreases the recurrence of Atrial fibrillation (AF) after electrocardioversion (ECV) in patients with AF.

This study will test the hypothesis that implantation of a subcutaneous implantable cardioverter defibrillator (S-ICD) without performing a defibrillation test is non-inferior to S-ICD implant with a defibrillation test with regards to the primary endpoint failed first shock in a spontaneous arrhythmia episode when implant position is confirmed with PRAETORIAN score.

This study seeks to provide evidence that use of Philips mobile cardiac outpatient telemetry (MCOT) devices may improve patient care for patients who present to emergency departments (EDs) with syncope, which is a temporary loss of consciousness also known as fainting or who present experiencing a near temporary loss of consciousness (near syncope). It is set up as a random controlled trial, which means research participants will be randomly assigned to receiving the device or usual care. Patients 50 years or older who come to the ED of Carilion Roanoke Memorial Hospital will be screened by study team members for unexplained syncope or near syncope across three ED dispositions: hospital admission, emergency department clinical decision unit admission (ED CDU) and emergency department. After consent, subjects will be enrolled and randomized, via REDCap randomization, in the study. At the time of subject discharge the MCOT device will be placed on the chest for the arm of intervention patients (for subjects who were admitted, the research study team will follow the patient's clinical course and placement of the device will occur at discharge); subjects will also receive brief instruction on the care and maintenance of the device and a patient education guide. The research team will contact the subjects for a telephone follow up at 14 and 30 days post-enrollment. The study will establish the efficacy of mobile cardiac outpatient telemetry in comparison to observation telemetry. Research objectives are to 1) Measure the time to medical intervention in patients with unexplained syncope or near syncope fitted with a Philips MCOT at the time of hospital discharge compared to patients treated with usual care for unexplained syncope or near syncope; and 2) Measure the time to arrhythmia diagnosis in patients with unexplained syncope or near syncope fitted with a Philips MCOT at the time of hospital discharge compared to patients treated with usual care for unexplained syncope or near syncope.

To detect atrial fibrillation after infection.

This study aims to evaluate the electrophysiological properties of the heart conduction system in patients with (increased risk of) ventricular tachyarrhythmias (VTA) and sudden cardiac arrest, and in a control cohort. The electrophysiological properties will be measured with the relatively new technique ECG-Imaging (ECGI). Moreover, clinical data of subjects will be gathered. By combining the data from the data gathering and the results of ECGI, the investigators hope to increase mechanistic understanding of and risk stratification for VTAs. The investigators aim to be able to identify patients at risk of an arrhythmic event, and aim for better treatment strategies in the future.

The purpose of this study is to determine whether early diagnosis of obstructive sleep apnea and initiation of and adherence to CPAP therapy in hospitalized cardiac patients would impact 30-day hospital readmission rates.

This research is being done to determine how well cardiac computed tomography (CT) scanning measures of fat within the heart can predict abnormal heart rhythms and how well cardiac CT can measure scar within the heart versus cardiac magnetic resonance imaging (MRI). People who have been enrolled in PROSe-ICD (NA_00045142) and Reynolds (NA_00037404) studies may join The procedures, tests, drugs or devices that are part of this research and will be paid for by the study

The study will evaluate the mean average error (MAE) of measuring pulse rate using the Norbert Device (ND) as compared to a reference heart rate measured using an electrocardiogram (ECG).

With the steady development of catheter ablation, it has gradually become the main treatment of various arrhythmias. Antithrombotic and anticoagulant therapy after catheter ablation determines the occurrence of perioperative bleeding and ischemic events. However, the incidence, characteristics and short-term prognosis of secondary acute cerebrovascular events in patients with arrhythmia after catheter ablation have not been studied. Methods: This study was intended to retrospectively collect and analyze the case data and auxiliary examination results of patients with arrhythmia who underwent catheter ablation. To evaluate the incidence, clinical features and short-term prognosis of secondary acute ischemic and hemorrhagic cerebrovascular events in patients with arrhythmia after catheter ablation. In order to improve the quality of life of patients, reduce the secondary acute cerebrovascular complications in the hospital in patients with arrhythmia after catheter ablation, to provide evidence for promoting the clinical management of such patients, and to provide help for the maximum degree of prevention and control risk.

In this study, the investigators evaluated the association between various measures of adiposity [BMI and waist circumference (WC)] and clinical outcomes in Asian patients who underwent pacemaker insertion, using a nationwide population based cohort.
